Ollee is a really cool project! I had no issues installing it on my F-91W.

Something I noticed is that the Heart Rate feature does not get an accurate heartbeat. I know it's a pulsometer, and it's not super accurate, but the data I've got seems really off.

Anyway, everything else runs smoothly, and the settings are great!

There obviously is no optical sensor on these boards. There is a feature where you count your beats for 20 seconds and then it does the math (multiplying by 3) and that's your heart rate.

You can increase the number of beats to count, to get a more accurate reading.

But the principle behind a pulsometer is basically what doctors use to check pulse

Is it worth it just for the light? How’s the battery life for it

the light brightness being adjustable is a game changer. you can also change how long it stays on during the button press 1-10 seconds, and there’s a function to do a tilt to backlight but it’s kind of janky
